It's not "constantly changing." It is quite well specified; you just
don't like what it is specified to be.

I don't even know what this sentence means.
If you are doing something relatively out of the norm (which you are),
then it's on you to read up on what the standard specifies the
behavior to be and act accordingly. What you are arguing against is
well-specified behavior. You just think it's suboptimal. That's
fine, but that doesn't change the fact that it is well-specified.
